To determine the rates and risk factors of complications related to cerebrospinal fluid drainage (CSFD) during first stage and completion fenestrated-branched endovascular aortic repair (F-BEVAR) of pararenal and thoracoabdominal aortic aneurysms. ⋯ Although CSFD is widely used to prevent ischemic spinal cord injury during complex aortic repair, the risk of major CSFD-related complications is not negligible and should be carefully weighed against its potential benefits. One-third of spinal cord injuries were caused by CSF drain placement. The use of fluoroscopic guidance may decrease the risk of CSFD-related complications.

Blunt carotid artery injury (BCI) is present in approximately 1.0% to 2.7% of all blunt trauma admissions and can result in significant morbidity and mortality. Management ranges from antithrombotic therapy alone to surgery, where potential indications include pseudoaneurysm, failed or contraindication to medical therapy, and progression of neurologic symptoms. Still, optimal management, including approach and timing, continues to be an active area for debate. The goal of this study was to assess the epidemiologic characteristics of BCI, and, after controlling for presenting features intrinsic to the data, compare outcomes based on management, operative approach, and timing of intervention. ⋯ In this study, there was no significant trend in the overall volume of operative or nOM; however, when considering approach to OM, there was a significant decrease in open procedures. Consistent with previous literature, injury to the neck, head, and chest was significant associated with BCI. Also outcomes demonstrated an increased prevalence of stroke after operative relative to nOM. Importantly, after critically assessing the timing to intervention, results strongly suggested that, if possible, intervention should be delayed for at least 24 hours.

Impact of hospital volume on patient safety indicators and failure to rescue following open aortic aneurysm repair.
Failure to rescue (FTR), a patient safety indicator (PSI) defined, codified, and adjudicated by the Agency for Healthcare Research and Quality, is classified as a preventable inpatient death following major complications. FTR has been reported to be a significant driver of postoperative mortality after open abdominal aortic aneurysm (OAAA) repair. The association between hospital volume (HV) and mortality is well known; however, the mechanisms responsible for these improved outcomes and relative contribution to observed interhospital variation is poorly understood. Similarly, HV influence on specific complications predictive of FTR is unknown; therefore, we sought to determine how HV influences risk and contributes to interhospital variation in PSI events leading to FTR and/or in-hospital mortality after OAAA repair. ⋯ OAAA FTR/30-day in-hospital mortality strongly correlated with annual case volume with higher volume centers having the lowest risk. Notably, HV accounted for a significant proportion of the observed variation in FTR and specific complications providing direct evidence for how the volume-outcome relationship may influence perioperative mortality. These findings can inform stakeholders to strategically enable them to implement processes of care directed at the most vulnerable patients that are designed to reduce the likelihood of preventable adverse events and death after OAAA repair. Furthermore, these results underscore the need to regionalize OAAA repair and potentially other complex operations, to HV centers because of their improved ability to rescue patients experiencing complications associated with postoperative mortality.

Patient and institutional factors associated with postoperative opioid prescribing after common vascular procedures.
Overprescription of postoperative opioid medication is a major contributor to the opioid abuse epidemic in the United States. Research into prescribing practices has suggested that patients be limited to 7 days or <200 morphine milligram equivalents (MME) after surgical procedures. Our aim was to identify patient or institutional factors associated with increased opioid prescriptions. ⋯ Opioid prescriptions at discharge vary with the invasiveness of vascular surgical procedures. Less than 25% of patients receive >200 MME. Variation by center represents a lack of standardization in prescribing practices and an opportunity for further improvement based on developed guidelines. Patient factors and procedure type can alert clinicians to patients at risk of higher than recommended MME.

Preoperatively detected sarcopenia as reflected by psoas muscle area (PMA) is associated with postoperative mortality after abdominal aortic aneurysm (AAA) repair. We studied, whether changes in PMA and lean PMA (LPMA) after endovascular aortic repair (EVAR) are associated with postoperative survival. ⋯ The most significant loss of skeletal muscle occurs during the first year after EVAR. The relative change in PMA from baseline is an independent predictor of mortality. For every 10% unit increase in ΔPMA/baseline CT muscle parameter bilaterally, there was a 21% decrease in the probability of death during follow-up. Early detection (from CT studies) and prevention of sarcopenia may potentially improve survival in EVAR-treated patients.
